You can change brush size/hardness interactively using ctrl+opt+LMB drag on Mac or opt+RMB drag on Win.

I wish there was the same option for opacity. Actual hotkey could be adjusted in preferences, something like

ctrl+opt+drag left-right: size / hardness / opacity
ctrl+opt+drag up-down: size / hardness / opacity

This is now possible in Photoshop CS6. HUD brush can now change opacity - [Control] + [Option] + click drag up/down with General>Preferences> "Vary Round Brush Hardness based on HUD vertical movement" unchecked:

So it's hardness or opacity but not both?

I understand there are only two dimensions (vertical and horizontal,) but perhaps size and hardness could stay as they were, and opacity could be added with the addition of a 3rd modifier key?

That's correct. I think they're running out of modifiers as the addition of the command key does HUD Color picker.

from Julieanne Kost's blogpost: http://blogs.adobe.com/jkost/2012/07/changing-the-brush-opacity-in-photoshop-cs6.html

"Of course you can also use the number keys on the keyboard to change the opacity of a painting tool. Tapping one number assigns the percentage of the hit number (1 = 10%, 2= 20% etc. and 0 = 100%). Tapping two numbers quickly will give you that exact amount (5 + 4 = 54%). Tapping 00 (zero-zero) in Photoshop CS6 will decrease the opacity to 0. Note: If you have a tool selected that is not a painting tool, these shortcuts will affect the Opacity on the Layers panel."

This way still uses keyboard shortcuts, and works great!
